Probability Distribution Calculators

Instructions: This Chebyshev's Rule calculator will show you how to use Chebyshev's Inequality to estimate probabilities of an arbitrary distribution. You can estimate the probability that a random variable \(X\) is within \(k\) standard deviations ...

Instructions: This Empirical Rule calculator will show you how to use the Empirical Rule to compute some normal probabilities. Please type the population mean and population standard deviation, and provide details about the event you want to compute ...

Instructions: Compute exponential distribution probabilities using the form below. Please type the population mean \((\beta)\), and provide details about the event for which you want to compute the probability for. Notice that typically, the ...

Instructions: This Normal Probability Calculator will compute normal distribution probabilities using the form below, and it also can be used as a normal distribution graph generator. Please type the population mean and population standard ...

Instructions: Compute poisson probabilities using the form below. Please type the population mean (λ), and provide details about the event you want to compute the probability for: Population mean (\(\lambda\)) Two-Tailed: ≤ X ≤ ...

Instructions: Compute t-distribution probabilities using the form below. Please type the number of degrees of freedom associated to the t-distribution, and provide details about the event you want to compute the probability for: Number of Degrees of ...
